hi doc !!! my age is 28 yrs and my weight is around 56 kg my height is 5'2 and i am suffering from thyoroid and pcod.my period are very regular and even after doing the relation between 13 20 days of my monthly cycle. I had not concieve. doc has advised me to take Corian 5000 on Day 11for artifical rupturing as size of ovary was (21*23 mm). I felt cramping in stomach on Day 13 and sonography reports showed that egg was ruptured and fluid found in POD. we had relation on Day 13 alost 48-50 hours after taking the injection. Whether making relation 48-50 hours after the injection is right window for concieving. but my cycle which was due on 18 th june 2011 before that i am feeling same symptoms of getting period , still is there any chance of getting pregnant.
